About this swimming hole
An alpine lake at the base of St. Mary's Glacier near Idaho Springs, reached by a short rocky hike from Fall River Road. The trail site lists swimming among the lake's features, and visitors describe a small beach area for summer dips. The water is snowmelt-cold even in August, so this is a polar-plunge spot with big scenery.
